precalc help (law of sines and cosines)

hard to explain without a diagram, but:
a point on the ground is 200 feet from a water tower
the angle of elevation to the top of the tower is 18 degrees
the angle of elevation to the bottom of the tower is 15 degrees
how tall is the water tower?
(i think the water tower is on a hill?)
thanks!
